ELECTRlCALLY-HEATED APPARATUS.

SPECIFICATION forming part of Letters Patent No. 693,144, dated February1'1, 1902,

. Application iiled April 16, 1901. Serial No. 56,122. (No model.)

To a/ZZ whom it may concern,.-

Beit known that LVIoToR MoNArH, a citizen of the Empire ofAustria-Hungary, residing at Vienna, in the Empire of Austria-Hungary,have invented certain new and useful Improvements in Electrically-HeatedApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of the present invention is an improvement inelectrically-heated cookingstoves, heaters, hair-curling ironssolderingirons, and the like, which consists in insulating the bodyforming the heating surface proper from the other parts of thementionedV apparatus by a poor conductor of heat, so that the passage ofheat upon the non-acting parts of the apparatus is prevented as much aspossible. a

In the accompanying drawing as an example a cooking-stove is shown incross-section to illustrate the present invention.

The heating-surface proper, a, is, as the figure shows, not in directcontact with the frame c of the apparatus; but interposed between a andc is a material b, which consists of any non-heatinginsulatingsubstance.The frame c as shown in this instance is provided with an inner ledge orsupport d inside the vertical plane ofthe upper inner wall of the frame,and a non-heating insulating slab or block b rests on this ledge andfits between said in= ner upper walls of the frame. The upper face ofthe body l) is hollowed out and contains the plate or body a to ,beheated. In the opposing upper faces of slab b and plate o, areregistering grooves, which together form receptacles for theresisting-bodies e, through which the electrical current is passed.

By this arrangement the transmission of heat upon the parts of theapparatus not be# ing designed to give heat is reduced to a minimum, andthus a considerable economy of energy is obtained over the knownconstructions of'similar apparatus.

I claim- An electrically-heated apparatus comprisL ing a frame c havinginner ledges d below the upper edges of its walls, a ynon-heat-conducting slab b resting upon said ledges and be tween said walls and hollowedout on its upper surface, and a plate a to be heated resting in thehollow of the slab b, the said slab and plate being provided in theirmeeting faces, with registering grooves forming receptacles to receivethe resisting-bodies e through which to pass the electric current,substantially as described. f

In testimony whereof I affix my signature in presence. of two witnesses.
